Received a faulty dehydrator that only circulated room temperature air even though it was supposed to be able to heat up to 70C. Emailed the customer service who said it may be a faulty heating element. As it was within 30 days of receiving the product, I asked for a return and refund, which was agreed by the seller that they would refund within 5 working days of receiving the return. Posted it off DPD tracked and then… nothing. I chased them up after the 5 working days and after 48 hours of the email, they admitted they’ve received it and has asked their finance arm to refund which should take another 5 working days. And then nothing. I sent another chaser. No reply even after 5 working days since. At this point, they’ve had the returned item nearly a month and still no refund. In the end, I had to escalate the issue to my credit card company with the string of emails exchanged including where the seller agreed to a refund, admitted they have received the item, the proof of return and signed-for delivery received on tracker.
